Advice??? Please

Lately I’ve been having stomach issues where I feel like I am constantly full- whether i’ve eaten or not. I’ve never been a big eater, and having been sick (cold) recently Ive been eating even less. When I do eat, I feel extremely full and get stomach cramps. It feels like I can feel my stomach, as if it’s a blown up balloon. I feel like my stomach is bulging out of my “belly”/ abdominal area. I’ve gotten the hiccups every day for the past week. I’ve lost 5 lbs already ( 5’ ft 6 inches, was 126ish, am now 121-122) and I am not sure when this becomes “important”

A little “background”- a couple years back I had many big spells of no appetite. I went to the doctor and they did tests and everything came back normal. I still have problems eating.

I’m not sure how important this might be. I’ve been struggling with energy levels lately. No matter how much sleep I get, I am exhausted. Any time I eat, I feel awful.

I would appreciate any insight I can get.
